【摘要】：子長(zhǎng)油田子115、子113井區(qū)主要開(kāi)發(fā)層系為長(zhǎng)2油層。本區(qū)油藏埋藏較淺,油井具有初產(chǎn)較高、遞減較快的特點(diǎn)。為達(dá)到提高油田開(kāi)發(fā)水平、提高采收率目的,就必須提高油藏描述水平,開(kāi)展儲(chǔ)層特征研究。本文在前人研究的基礎(chǔ)上,開(kāi)展了地層精細(xì)劃分對(duì)比與構(gòu)造特征、儲(chǔ)層沉積相研究、地質(zhì)約束的測(cè)井儲(chǔ)層評(píng)價(jià)及二次處理和儲(chǔ)層綜合評(píng)價(jià)等基礎(chǔ)研究工作。研究中利用了區(qū)域標(biāo)志層K9和輔助標(biāo)志層開(kāi)展了精細(xì)地層劃分和對(duì)比工作,建立的60條地層對(duì)比剖面,實(shí)現(xiàn)了全區(qū)地層對(duì)比的閉和與一致性。確定了研究區(qū)的油水層判別標(biāo)準(zhǔn)和物性下限標(biāo)準(zhǔn),開(kāi)展了測(cè)井資料二次處理,建立了研究區(qū)儲(chǔ)層參數(shù)靜態(tài)數(shù)據(jù)庫(kù)。為子長(zhǎng)油田下一步科學(xué)開(kāi)發(fā)提供充分的理論依據(jù)。
[Abstract]:In Zichang Oilfield, Z115, Z113 well area is mainly developed by Chang 2 reservoir.The reservoir in this area is shallow buried, and the oil well has the characteristics of high initial production and fast decline.In order to improve the level of oilfield development and enhance oil recovery, it is necessary to improve the level of reservoir description and study reservoir characteristics.On the basis of previous studies, this paper has carried out the basic research work, such as fine stratigraphic division and correlation and structural characteristics, reservoir sedimentary facies, logging reservoir evaluation with geological constraints, secondary processing and reservoir comprehensive evaluation, etc.In the study, the fine stratigraphic division and correlation work were carried out by using regional marker layer K9 and auxiliary marker layer, and 60 stratigraphic correlation sections were established, which realized the closure and consistency of stratigraphic correlation in the whole area.The criteria of oil and water reservoir discrimination and the lower limit of physical properties are determined, the secondary processing of logging data is carried out, and the static database of reservoir parameters in the study area is established.It provides sufficient theoretical basis for the next scientific development of Zichang Oilfield.
